Following Banakh and Gabriyelyan (Monatshefte Math 180:39–64, 2016), a Tychonoff spaceXis Ascoli if every compact subset ofis equicontinuous. By the classical Ascoli theorem everyk-space is Ascoli. We show that a strict (LF)-spaceEis Ascoli iffEis a Fréchet space or. We prove that the strong dualof a Montel strict (LF)-spaceEis an Ascoli space iff one of the following assertions holds: (i)Eis a Fréchet–Montel space, sois a sequential non-Fréchet–Urysohn space, or (ii). Consequently, the spaceof test functions and the space of distributionsare not Ascoli that strengthens results of Shirai (Proc Jpn Acad 35:31–36, 1959) and Dudley (Proc Am Math Soc 27:531–534, 1971), respectively.
